To be clear, this is an issue which manifests at build time, so it is a hard blocker for glibc development. Torvald,
Could you please have a look at this?

Add pretty printers for the NPTL lock types
We now have pretty printers for the NPTL lock types, and we need subsequent changes to them to match the new condvar implemenation.
Effectively it's a new requirement on any implementation changes.
There are now also tests for these e.g. nptl/test-*-printers* which use gdb and python (expect framework) to drive gdb and a coupled test.
So I suppose we need new patches for condvar and rwlock, which we'll then use instead of the old ones for Rawhide. I'll put it on my list. I have a workaround with which I can build glibc in rawhide. I'll use that for the time being. It means that we currently do not have the pretty-printers installed. This is fixed upstream:

New condvar implementation that provides stronger ordering guarantees.
Which has pretty printer support rolled in.
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'. This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '26'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 26 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. |
